Applying ozone to your tank raises the ORP, increasing oxygen levels and decreasing dissolved wastes; ozone also effectively kills bacteria and other harmful pathogens and breaks down ammonia and organic waste materials, AquaZone ozonizer`s corona discharge technology provides higher ozone concentration than UV bulb style ozonizers and allows variable ozone output.

One of the most visible results of ozone as part of aquarium filtration is the change in the water's color from an unappealing yellow cast to a healthy-looking natural clear color.
